Quasi-Experimental Design
A variable with levels to which participants are not randomly assigned and that differentiates the groups or conditions being compared in research
What is...
Quasi-independent variable
Developmental design that combines longitudinal and cross-sectional techniques by observing different cohorts of participants over time at different or overlapping ages
What is...
Cohort-sequential design
A participant serves as his or her own control and the DV measured is analyzed for each individual participant, and is not averaged across groups or across participants
What is...
Single-case experimental design
The size of the change in a dependent measure observed between phases of a design
What is...
Magnitude
Randomization
Manipulation
Comparison/control group
What are...
The three elements of control OR
Elements of experimental designs
DV is measured for one group of participants following treatment
in other words...
A treatment is delivered to one group, containing a quasi independent variable, then measured
What is...
One-group posttest-only design
Developmental design where participants are grouped by their age and participant characteristics are measured in each group
What is...
The cross-sectional design
Treatment is successively administered over time to different participants, for different behaviors, or in different settings
What is...
Multiple-baseline design
Consistency in the pattern of change in a dependent measure in each phase of a design
What is...
Stability
Consent of a minor or other legally incapable person to agree to participate in research only after receiving an appropriate explanation in reasonably understandable language
What is...
Assent
The same DV is measured in one group of participants before and after a treatment is administered
What is...
One-group pretest-posttest
A developmental design used to study changes across the life span by observing the same participants at different points in time and measuring the same DV at each time
What is...
Longitudinal design
A single participant is observed before, during, and after a treatment or manipulation
What is...
ABA design OR Reversal design
A ___________of the data, not inferential statistics, is used to analyze the data when only a single participant is observed
What is...
A visual inspection OR graph
Ethical principle ensuring benefits of research are maximized and costs are minimized
What is...
Beneficence
A control group that is matched upon certain preexisting characteristics similar to those observed in a treatment group, but to which participants are not randomly assigned
What is...
Nonequivalent control group
DV is measured at different points in time in one group before and after a treatment that naturally occurred
What is...
Interrupted time series design
Baseline phase is followed by successive treatment phases in which some criterion or target level of behavior is changed from one treatment phase to the next. The participant must meet the criterion of one treatment phase before the next treatment phase is administered
What is...
Changing-criterion design
The research method you would use to conduct a study that identifies the best teaching method for a specific student.
What is ...
Single-Case Experimental Design
The manipulation of a variable, holding all other variables constant
What is...
Control
DV is measured at many different points in time in one group before and after a treatment that is manipulated by the researcher is administered
What is...
Time series design
DV is measured in one group of participants before and after a treatment and that same DV is also measured before and after in another nonequivalent control group that does not receive the treatment
What is...
Nonequivalent control group pretest-posttest design
Level of control of a single-case design can be determined when the following two features are observed in a graph
What are...
Stability and Magnitude
Using a single case design, a psychologist examines the extent to which characteristics of child play behavior during recess generalize to characteristics of play behavior during class time. In this example, the psychologist is generalizing across
What are...
Settings
The extent to which a research design includes enough control of conditions and experience of participants that it can demonstrate a single unambiguous explanation for manipulation- that is cause and effect
What is...
Internal validity
